BETHLEHEM, Pa. -- A day after DeSean Jackson was carted off the field at Eagles training camp, cornerback Asante Samuel and running back Mike Bell had to be taken off the field via cart.

The team said both suffered hamstring strains.

"I'm not a mad scientist," Samuel said after practice. "I might be out there tomorrow."

Most troubling injury of the weekend:

Ryan Howard’s ankle

Raul Ibanez’s wrist

Mike Bell’s hamstring

Stewart Bradley’s hamstring

DeSean Jackson’s back

Asante Samuel’s hamstring

Bell left the locker room with his entire leg wrapped. Asked for an update on the injury, "He said, 'I'm alright.'"

During 7-on-7 drills, Bell caught a pass from quarterback Kevin Kolb out on the flat and turned up field as he ran away from linebacker Keenan Clayton. As he accelerated, he let out a yell and immediately grabbed the back of his thigh.

Bell fell to the ground on the sidelines where he was treated by the Eagles training staff. As he got into the cart he yelled a few words not printable for the Internet.

Bell, who was acquired in the off-season as a restricted free agent, had impressed thus far at camp. He's a hard running, north-to-south back that was expected to complement starter LeSean McCoy.

Guard Max Jean-Gilles and center A.Q. Shipley also suffered injuries during the afternoon practice. Jean-Gilles, who had lap band surgery in April, left because of dehydration, the team said, and Shipley had an ankle sprain.
